2 Micro Series Introduction DADO produces top quality products at competitive prices and provides a superior level of customer service. Founded in 18, DADO is the highest volume producer of gas springs for press tools. DADO s products are widely approved and used in global operations for many industries including metal stamping, automotive and plastic injection molding. Advanced Technology DADO s revolutionary Micro provide unparalleled versatility in industrial tools. The patented design offers unmatched performance in high quality dies, molds and machines. vs. oil Springs DADO s Micro easily replace conventional coil springs. Micro Springs deliver more force in less space than coil springs and one Micro Spring can provide the force of several heavy-duty coil springs. See page 3 for oil Spring conversion information. Range of Micro Sizes DADO s Micro are available in eight models. Model Micro 4 Micro 70 Micro 0 Micro 180 Micro 20 S.16 E.16 E.

The Micro 4, Micro 70, Micro 0, Micro 180 and Micro 20 gas springs are color-coded for easy identification of force rating and are shipped ready to install. No additional equipment or previous experience with nitrogen is required. DADO offers adjustable force models that can be customized to meet individual force requirements. The adjustable model may be set to the desired pressure at the factory or in the field with appropriate charging equipment. See page 18 for more information on charging Micro Springs. Threaded Body DADO s Threaded Body models are ideal part ejectors, replacing conventional coil spring stock lifters. The E.16, S.16 and E. are designed with domed rods to further facilitate part removal during operation. DADO provides a variety of hex tools, shown on page 17, that allow for easy installation and removal of the Threaded Body models. ost Effective DADO Micro Springs are inexpensive, easy to install, and provide a cost-effective solution to downtime problems associated with other springs. No Preloading Required DADO Micro Springs deliver full rated force on contact with no preloading required. Occasionally, slight preloading is recommended, especially for stroke lengths from mm, to prevent full spring travel where material thickness varies and parts can stick (i.e. stripper applications). Rod Wiper Fights Draw ompound DADO s Duralene Rod Wiper excludes most draw die compounds. For applications where an aggressive draw die compound is used contact DADO for alternative wiper options. Guaranteed ong ife In factory testing and field experience, the service life of DADO s Micro Springs consistently exceeds one million strokes. This is supported by DADO s written One Year/One Million Gold Guarantee. ontact DADO or your representative for more information.

All tool designs must be individually engineered for their intended function. See pages 1-20 for recommendations and limitations for mounting and installation. oil Spring onversion Unlike coil springs, DADO Micro provide full rated force on contact. This force is repeatable, eliminating scrap and maximizing productivity. One Micro Spring can provide the force of several heavy duty coil springs, and will outlast the coil springs. Most die springs have a limitation on compression, after which there is failure or severely reduced cycle life. Heavy and extra heavy duty die springs can only be compressed 1-20% of the closed height, after which there is failure or severely reduced cycle life. oil spring force is based on the spring rate of the coil spring. Spring rate is determined by the material, wire diameter, spring diameter, number of coils and height of the coil spring. Pc, Preload Free ength Diameter 1 - Sc 2 losed Height OA Pc Sc All coil springs require a preload to achieve a contact force (1) larger than F1 zero. For most spring applications the preload force is the force required - Sg to strip, hold, form or return the part. As a result of the spring rate, coil F2 springs have a continuing increase in force after preload (1-2). losed Height Diameter FORE F2 2 F1 1 Sg Gas Spring oil Spring TRAVE DADO Micro Series Gas Springs have a much flatter curve that will not exceed 30% of the original force for any stroke size (F1 - F2). When retrofitting coil springs calculate the total preloaded force required for the application. The number and color (load rating) of Micro Gas Springs can then be determined. 3

18 Micro Series harging Information AUTION: Always wear safety goggles when performing any maintenance work on gas springs. harging Micro Gas Springs When filling the Micro Spring, initially fill with low pressure (< 4 bar or 70 psi) to extend rod fully; then fill to desired pressure. Hold the spring vertically at all times during filling (Fig. 1). The Micro Spring charging pressure range varies by gas spring model. Verify range before charging. All Micro Springs should be inspected before recharging. Do not recharge gas springs if damaged. Refer to discharging instructions below for proper disposal. Use the Quick Disconnect harging Nipple and the High Quick Disconnect harging Assembly to charge the Micro Spring to the appropriate pressure (Fig. 2). Quick Disconnect harging Nipple Use the DADO Quick Disconnect harging Nipple to charge the Micro Series Gas Spring. For more information contact DADO. M6 Thread Fig. 1 Fig. 2 DADO harging Adapter Use the DADO harging Adapter to easily charge and discharge pressure in DADO s Micro Series Gas Spring. Not recommended for checking pressure due to small size of Micro Series Gas Springs. High Quick Disconnect harging Assembly Use the DADO High Quick Disconnect harging Assembly, , with the harging Nipple or harging Adapter to charge self-contained gas springs.

MAX Side loading from axial or contact misalignment should be minimized, <1. It is necessary to have a flat surface against the base of the spring in all circumstances. Incorrect pockets may cause structural damage or reduced life. All properly installed mounts (RM, NF, FA, RF, TB) support the load. No back-up is required. Retain inverted cylinders as shown with M6 cap screw. A close tolerance hole is required, depth > /2. Mounts such as the DADO-OK may be used to retain the spring from rod end. If possible use a positive stop. Improper Installation Examples ontaminants X X X X GAP GAP DRAIN HOES Verify the cap screw length. Uncontrolled Release Avoid large gaps in the upper. Use the tapped hole in the base to secure and preload if possible. INDUES SIDE OADING Do not constrain the rod end. Do not use the bottom mount in an unsupported or open mounting application. FAT BOTTOM Provide adequate drainage in gas spring pockets. Direct contact with certain die lubricants and cleaners can be harmful to gas springs or may cause pressure increase. If parts are jamming, determine the root cause and repair it XX before production continues. Failure to repair the problem will cause failure or damage of the gas spring. Preloading the pad will prevent gas spring damage from snap action or sudden release. Restricting rod travel will help prevent spring damage. X X X Sudden release will cause the gas spring to exhaust. Never compress the gas spring in a vice or clamp outside of the die. Never strike the rod with a hammer to test for pressure; damage can result. 1
